BEAM CONSTRUCTION.

Application filed March 6, 1922. Serial No. 541,277.

To all whom it may concern:

Be it known that I, WALTER I. TU'rTLn, a citizen of the United States,and a resident of Providence, in the county of Providence and State ofRhode Island, have invented an Improvement in Beam Construction, ofwhich the following is a specification.

This invention relates to construction of warp beams and the like.

One of the objects thereof is to provide apparatus of the above natureof strong and durable construction. Another object is to provide aconstruction of the above nature which is light and thereby efficient inaction, yet well adapted to meet-the conditions of hardest, practicaluse. Another object is to provide a construction of the above natureemploying wooden members with proper metal reinforcement to add strengthand rigidity where they are most needed. Other objects will be in partobvious and in part pointed out hereinafter.

The invention accordingly consists in the features of construction,combinations of elements and arrangement of parts as will be exemplifiedin the structure hereinafter described and the scope of the applicationof which will be indicated in the following claims. l

In the accompanying drawing in which is shown one of the variouspossible embodiments of this invention,

Figure 1 is an end elevation of a warp beam;- and Figure 2 is atransverse sectional view along the line 22 of Fig. 1 with certain partscut away.

Similar reference characters refer to simi lar parts in both views ofthe drawing.

Referring now to the drawing in detail, there is shown in section inFig. 2 the end construction of a warp beam, it being understood thatboth ends are identical, and one end only being shown in order to avoidencumbering the drawing. The barrel member or cylinder of the beam isshown at 10 and may be of any desired specific structure, such as thatof a hollow wooden type built up of a number of sectors. A shaft 12reaches the entire longitudinal extent of barrel 1Opassing'substantially through its center and also extends a substantialdistance beyond either end of barrel 10. Inside barrel 10 and adjacentits end there is preferably mounted a wooden abutment 11 secured to theinside surface of barrel 10 and provided with an opening at its centerthrough which shaft 12 passes. Likewise mounted inside barrel 10 thereis shown a clutch member 13 preferably secured to the face of abutment11 as by means of screws 29. Mating with clutch member 13 is a clutchmember 14 which will be hereinafter described.

Referring now to the head of the beam, there is shown resting againstthe end of barrel 10 a metal head member 15 which is preferably a solidmetal disk of substantially the diameter of the head. Snugly contactingwith the surface of disk 15 is shown a head member comprising preferablya plurality of built-up wooden elements as 16, 17 and 18. Each of theseelements comprises a plurality of wooden members resting edge to edge toform a disk of diameter slightly less than that of disk 15. The threewooden disks are preferably so assembled that the grain of the wood indisks 16 and 18 is substantially at right angles to the grain in disk17. The individual elements of disks 16, 17 and 18 may besecuredtogether by glue or by other suitable means. The periphery of metal disk15 is preferably flanged to extend over the peripheries of wooden disks16, 17 and 18, and this flange extends downwardly toward the axis of thedisks and then upwardly to form a groove '19 extending completely aroundthe periphery of the head. Groove 19 thus provides a belt race throughwhich the beam is driven. There is prefen ably inserted between theflange forming belt race 19 and the wooden head members a resilientfiller 20, for instance of gutta percha or rawhide.

Resting against the outer surface of wooden disk 18 are shown apluralityof radially extending metal arms 21 which are preferably bentinwardly at their outer ends to support belt race 19 and are tapered tointerfit about shaft 12 at the center of the head as shown in Fig. 1. Aplurality of rivets 22 connect each of arms 21 to disk 15 and upon beingheaded into position, securely and dependably clamp the three woodenelements therebetween. Rivets 22 are preferably countersunk in arms 21and in disk 15 to avoid projectin parts which might interfere with theoperation of the beam. It will be seen that a head structure built up inthis manner e'modies the lightness and consequent flexibility which isessential in beam construction and that the same is yet dependablyrein-forced where reinforcement is most needed to insure a strong andsubstantial structure.

The complete head thus built up as above described is provided with abore 23 at its center through which shaft 12 passes.

Shaft 12 is threaded as at 25 to receive a nut 26 (omitted in '1 ig. 1),'andthe end 28 is adapted to rest rotatably in suitable trunnions.

Referring now to clutch member 14 before mentionech'it is shownas beingguided into clutch member 13 by shaft '12 passing therethrough. Clutchmember 14 preferably contacts with the surface of disk 15 and isprovided with a pair of lugs 27 registering with openings in disk 15 andslightly entering'wooden head member 16. Thus, as nut 26 is threaded onto sh aft 12,'the head moves along shaft 12 and head member 15 forcesclutch member 12% into engagement with clutch member 13 and in thismanner the head and barrel members are easily assembled and a positivedriving connection is made'therebetween. As described above, the beam isdriven through the head member by meansof belt race 19. The drivingforce is transmitted from the :head through the clutch 14-13 to barrelmember 10.

It will thus be seen that there is herein provided an apparatus whichembodiesthe Various features of the invention, which apparatus in itsaction attains'the various obj ects of the invention and is welladaptedto meet the requirements of hard, practical use.

As many possible embodiments might "be madeof the above invention and asmany changes might be made in the embodiment above set forth, it is tobe understood that all matter herein set forth or shown in theaccompanying drawings is to be interpreted as illustrative and not in alimiting sense.
